Export images with higher resolution #326

Closed adrianusler closed 2 months ago

adrianusler commented 4 months ago

In think that this requires something like a virtual openGLWidget that is larger than the displayed one. One could then maybe call makeCurrent() on this one and grab the framebuffer from there? I'll see what can be done.

Update: I found a solution and will implement this soon! Update: See PR #373. But I need to implement some tests before we can merge it.

It might be possible to render to a separate framebuffer. However I do not know if there are any routines to export this framebuffer as png.

@Michel-Heinz apparently, the openGL-context must be part of a window. So I guess I have to add a "virtual" (i.e., permanently hidden) Gui form to the mix and render images on that when it's needed.

Technically, this is a duplicate of #221. But since we have had a discussion here, I will close #221 (even though it is older).
